Commentary

A polymer obtained by nucleophilic substitution reaction ofhydroquinone and4,4-difluorobenzophenone, in which benzene rings are connected by ether and ketone bonds. It has a very low VOC content and is therefore highly pure.

Key points

  • There is no molecular weight degradation even at high temperatures/high water vapor levels.
  • The continuous use temperature is also high at around 250°C, and the material is self-extinguishing.
  • In addition, it resistant to chemicals, radiation, metal ion contamination, and abrasion.
  • It can meet the strict requirements of special environments such as the aerospace and semiconductor industries.
